How Many Calories Are in a Boiled Egg? Sizes, Whites, and Yolks

One large boiled egg has about 78 calories, a medium has 70, and a small has 62. Size accounts for the main difference, while the yolk supplies roughly 78% of a large egg’s calories.

This guide gives you side-by-side counts, practical portion totals, and guidance for choosing a value that fits your egg size and nutrition log.

Calorie Counts for Whole Boiled Eggs

A standard large egg contains about 78 calories. The medium and small estimates fall to 70 and 62 because their edible weights are lower.

These estimates come from USDA FoodData Central entries based on edible weight. Package sizes can vary within a category, so 78 calories works as a practical value for a large egg rather than an exact measurement of every shell.

Your carton’s size label should guide the count. Use 78 calories for a large egg, 70 for a medium egg, or 62 for a small egg, then adjust the total for your number of eggs.

How Egg Size Affects the Count

A large egg has about 16 more calories than a small egg because its edible white and yolk weigh more. A consistent edible-weight comparison keeps that difference from being confused with cooking or added ingredients.

The shell does not enter the edible serving or its calorie total. Weighing an unpeeled egg includes material you discard, so a peeled weight or package category gives you a more useful basis.

Seven large eggs total about 546 calories. Seven small eggs total about 434, which leaves a 112-calorie difference based on egg size alone.

For a daily food log, that difference can affect your calorie allocation even though each egg also changes the portion’s protein and fat. Record the category your package uses so your totals remain consistent from week to week.

Calories in Egg Whites and Yolks

One large egg white has about 17 calories, compared with about 61 in one large egg yolk. The yolk therefore contributes roughly 78% of the 78 calories in the whole egg.

Three large whites contain about 51 calories, while three whole large eggs contain 234. These servings are not equal in weight because each whole egg adds a yolk, which carries most of the fat and calories.

Removing the yolk drops one large egg from about 78 calories to 17. You retain nearly all the egg’s protein, but the serving loses the yolk’s fat, cholesterol, choline, and several vitamins and minerals.

A yolk-only serving gives you the opposite result. One large yolk supplies about 61 calories, so eating several whites alongside it changes the portion from egg-centered protein to a mixture dominated by yolk calories.

Once the yolk and whites are accounted for separately, cooking method can further shift how those nutrients translate into each prepared serving.

Cooking Methods and Nutrient Content

Hard-boiling, soft-boiling, or gently heating an egg leaves its calorie count close to the raw egg’s total. Heat changes proteins and makes the egg safe to eat, but it does not add a meaningful amount of energy by itself.

Protein, Fat, and Micronutrients

With about 6 grams of protein and 5 grams of fat, a large boiled egg is a nutrient-dense choice. It contains very little carbohydrate plus cholesterol, choline, vitamin B12, selenium, phosphorus, and riboflavin.

Two large boiled eggs provide about 12 grams of protein and 10 grams of fat. Your calorie total remains about 156 without cheese, butter, oil, mayonnaise, sugar, or sauce.

Egg protein carries a high biological value because it contains essential amino acids in proportions your body can use. The yolk also contributes fat-soluble nutrients, so removing it changes the nutrient profile as well as the calorie count.

Portion size still controls the total you record. Two medium eggs provide about 140 calories, two small eggs provide about 124, and three medium eggs provide about 210.

Calories Added With Toppings

Plain boiling leaves the egg near 78 calories. Calories rise only after ingredients such as butter, mayonnaise, cheddar cheese, oil, or a sugary sauce enter the serving.

You can separate the egg from its toppings in your food log. That approach preserves the plain egg’s value while showing how one tablespoon of mayonnaise adds 94 calories to the plate.

Calories for Common Egg Portions

Multiplication gives you a quick total for whole eggs. Two large eggs contain about 156 calories, and three contain about 234, while three medium eggs contain about 210.

Whole-Egg Serving Totals

• ▸One large egg: Record about 78 calories for one peeled whole egg.
• ▸Two large eggs: Multiply 78 by 2 for about 156 calories.
• ▸Three large eggs: Multiply 78 by 3 for about 234 calories.
• ▸One medium egg: Record about 70 calories for a standard medium serving.
• ▸One small egg: Record about 62 calories for a standard small serving.

Your choice of egg size changes each total. Two medium whole eggs equal about 140 calories, while two small whole eggs equal about 124.

Mixed White-and-Yolk Portions

Two whole large eggs plus one large white contain about 173 calories. You calculate the total as 78 plus 78 plus 17, counting each physical component separately.

A breakfast with two large whites, one large yolk, and one whole medium egg contains about 164 calories. The separate whites contribute 34, the yolk adds 61, and the medium whole egg contributes 70.

Three large whites, one large yolk, and one whole medium egg contain about 182 calories. The arithmetic gives you 51 from the whites, 61 from the yolk, and 70 from the medium egg.

Those portion totals provide the baseline, but a reliable food-log estimate also depends on applying them consistently to the actual serving.

Choosing an Accurate Nutrition Estimate

A carton’s size category and stated serving weight provide the best basis for your estimate. A package listing one 50-gram large egg matches the 78-calorie value more closely than a generic database serving does.

Check the Serving Basis

• ▸Identify the serving: Confirm that an entry represents one physical egg instead of several.
• ▸Check the weight: Look for about 50, 44, or 38 grams to match large, medium, or small eggs.
• ▸Separate the parts: Distinguish a whole egg from a white, yolk, or mixed serving.
• ▸Exclude the shell: Record only the edible egg because the shell contributes no nutrition.
• ▸Round once: Use 78, 70, or 62 calories as a simple whole-egg baseline.

“Database values can conflict because some list one 50-gram egg, while others use a small portion measured by weight. Read the serving description before comparing two totals.

Per-100-gram listings create another common source of confusion. A 50-gram portion uses half of a 100-gram value, whereas a 38-gram egg uses a smaller fraction.

Food Standards Agency tables can express nutrition values per 100 grams. You must convert that figure to the edible weight of your egg before entering it in a calorie log.

Your quickest method uses one category throughout your log. Choose 78, 70, or 62 calories, multiply by the number of whole eggs, and count separated whites or yolks on their own.

Hard-boiled, soft-boiled, and gently cooked eggs do not differ meaningfully in calories from each other. The meaningful differences come from egg size, the yolk’s share, serving count, and ingredients added to the plate.

Key Takeaways for Your Food Log

Your standard values are 78 calories for a large boiled egg, 70 for a medium egg, and 62 for a small egg. These totals cover the edible whole egg without the shell.

A large white contributes about 17 calories, while its yolk contributes 61. Removing the yolk cuts the serving from 78 calories to about 17 and changes its protein, fat, cholesterol, and micronutrient content.

Use package data where available, count each separated component, and include toppings in a separate line. This method gives you a consistent number without confusing the shell, cooking method, or serving weight with the egg itself.
